A new adaptive mesh technique for searching for a bistatic specular point on a convex hull surface has been developed for the High Frequency Target Acoustic Model HFTAM. The existing method of bistatic specular point searching in the HFTAM uses a bisection search with numerical evaluations of a transcendental equation at each bisection step. This method has been shown to lack computational robustness. An adaptive mesh technique has been implemented with the HFTAM and has been shown to be more robust than the bisection technique. This report describes the new version of the HFTAM and the equations used in the model it also provides guidelines for software implementation.
